Chapter One : Connecting Your Devices
Connecting an External Infrared Receiver and IR Repeaters (VR-4090 and VR-4080 only), continued
Your new audio-video receiver supports the IR-9991 two-
way external infrared (IR) remote transceiver control. The
IR-9991 enables you to use the Receiver's Remote Control
unit to operate the receiver if it is:
• in a stereo closet/cabinet
• behind glass doors
• in another room
• in any situation where the device to be controlled is
not visible
You can substitute Xantech (291-80, 480-30, or 490-30 se-
ries) IR receivers for the IR-9991. However, these devices are
one-way only, and will not supply system status feedback
to Remote Control unit.

To Connect a KENWOOD IR-9991 IR Receiver:

1. Connect the IR-9991's IR IN cable to the receiver's IR
RECEIVER IN jack. This jack supports a 12V 20mA sig-
nal.
2. Connect the IR-9991's IR OUT cable to the receiver's IR
OUT LCD REMOTE jack.
3. Connect an AC adapter to the IR-9991. Do not plug the
adapter into the wall until all connections are made.
4. To activate the IR receiver connections, you need to press
INPUT MODE key on the front panel of the receiver for
more than 2 seconds.
• VR-4090/VR-4080 : You will see "RF OFF" on the re-
ceiver display.
• KRF-V7773D for U.S. Military : You will see "DATA
REAR IN" on the receiver display.

To Connect any other IR Receiver:

1. Connect the IR receiver's output cable to the receiver's
IR RECEIVER IN jack. This jack supports a 12V 20mA
signal.
2. Connect an AC adapter to the IR receiver. Do not plug
the adapter into the wall until all connections are made.
3. To activate the IR receiver connections, you need to press
INPUT MODE key on the front panel of the receiver for
more than 2 seconds.
• VR-4090/VR-4080 : You will see "RF OFF" on the re-
ceiver display.
• KRF-V7773D for U.S. Military : You will see "DATA
REAR IN" on the receiver display.

To Connect IR Repeaters:

IR repeaters enable you to control components located in
cabinets or behind glass doors. To connect repeaters:
1. Connect the IR repeater to the device as described in the
repeater's manual.
2. Connect the IR repeater cable(s) to the Receiver's IR
REPEATER OUT jack(s).
IR repeaters send a signal similar to the device's own re-
mote control. Xantech repeaters (models 282-00, 286-00,
or 283-00) are compatible with your new audio-video re-
ceiver.
Do not connect IR repeaters unless you have connected an
external IR receiver. The connections are only active when
an IR receiver is connected.
